97.0. "REGA design fault ???" by LARVAE::JEFFERY (K-I-L-L-E-D, Revoked) Tue Jun 20 1989 09:48

    I've recently had trouble with my REGA II. Last week, I went to
    play a record, and I noticed that the platter wasn't turning (I
    usually leave it on all the time). I checked the mains wiring, and
    it seemed OK.
    
    I'd heard all about the REGA lifetime guarantee, and I must admit
    was a little nervous about whether it was true or not. I rang Reading
    HiFi, and they suggested I bring it in. I left it with them, and
    just when I got back to my house, they rang me and said it was ready!!
    I was so pleased with the free repair, that I changed my cartridge
    for a REGA Bias (more on that later).
    
    The fault was minor. The REGA has a simple circuit with I imagine
    a resistor to bring the voltage down, and a capacitor to filter
    noise. Anyway, REGA's apparently often develop this problem, and
    they send large stocks of replacement resistors to all their dealers.
    
    So in one sense, I am relieved that it didn't cost me anything,
    but in another, I am annoyed that there seems to be a design fault.
    Can anyone with more knowledge of electronics comment on this.
    
    I think an electronic power supply would help.
    
    Cheers.
    
    Mark.
    
    P.S. Reading HiFi have moved to much more spacious premises, and
    are an infinite improvement on the old shop. The staff were friendly
    and helpful.

97.1	Rega 3 Main bearing trouble	JUNO::JUNO::HAYES		`Mon Jun 10 1991 10:04`	13
	I thought I'd put this here instead of starting a new note, I've got a Rega 3 which I bought ex-demo a year and a half ago. And I've just started to notice some play in the main bearing, not much, but I'm sure it wasn't there when I bought it. Question1: does anybody know if it should be like this? Question2: If it is a problem, I think I'll try and get a new bearing from Rega, does anyone know how much, and Rega's address? Thanks, Chris.

	Main bearings sometimes have a tiny bit of play before you charge them with oil. Otherwise they don't have any detectable play. Is this one dry? If so, should it be? Nick
97.3	You should have no problems.	CRATE::WATSON	Blood on the Rooftops	`Mon Jun 10 1991 20:52`	24
	Sorry I didn't reply earlier I must have been asleep. The should be absolutly no play on a Rega bearing what so ever (At least to the hand). The main bearing of the Rega-3 is the most expensive part of the '3 becaue it is machined to such a precision - it should have a mirror like apperance�. Do not dispare thought - as it is ex-demo you should have no trouble getting the thing replaced FOC. ALL Rega dealers are of the highest quality (There are only 22 (?) dealers in the UK - all hand picked) If you have any difficulty then get Rega's number from your dealer (Chris Brooks Audio could tell you - 0925-61212) ask to speak to the service dept. If this fails then speak to Roy Gandi (?sp) at Rega - he's the boss tell him your situation - he is a very nice guy - more than willing to help. Hope this helps, Rik. �Not that you should remove the bearing as it can take hours to replace - such is the precision.
97.4	good point	JUNO::JUNO::HAYES		`Tue Jun 11 1991 10:31`	8
	Any ideas how much oil. And what sort? When I bought the turntable, they couldn't find the instructions(what a loss) but therefore I don't know how often it should be lubricated. Cheers. Chris.
97.5	cheers for the info Rik.	JUNO::JUNO::HAYES		`Tue Jun 11 1991 10:33`	0
97.6	Ho Hum (Linn K9/Rega 3)	XSTACY::PATTISON	Where's me jumper?	`Tue Jun 23 1992 16:54`	7
	As good a place as any... Anyone know anything about Rega arms and cartridge "hum"? Dave
97.7	Try an earth	FORTY2::SHIPMAN	MOG	`Tue Jun 23 1992 17:15`	15
	Yep, Rega arms sometimes hum. I seem to remember they come without any earth connection, and you can improve matters by fitting your own. Try attaching a thin, flexible wire to a suitable piece of exposed metal at the arm base. Thin and flexible to avoid coupling the armboard to whatever the wire touches - it'll make a difference even on a Planar. As to where to connect the other end, you may have to experiment (with the volume down...): you can try some metal on the deck (eg the earth screw if it uses one), the earth screw on the preamp, or one of the phono plug screens. I had to do this once with an RB250/ATxx on my Rock Reference while it was waiting for its Excalibur/Dynavector 17D2. It worked, but still wasn't completely quiet. Nick

	Ok, I'll give it a try. Dave
